For courses in Theories of Development at the undergraduate or graduate level. As a supplement to Child/Life Span/Adolescent Development courses or for any course where instructors need additional coverage of developmental theories. The result of extensive scholarship and consultation with leading scholars, written in an engaging narrative for undergraduates and graduates alike, this text introduces students to twenty-four different theorists and compares and contrasts their theories on how we develop as individuals. Emphasizing the theories that follow and build upon the developmental tradition established by Rousseau, this text also covers theories in the environmental/learning tradition.
